"Voter ID laws definitely can lead to the disenfranchisement of certain communities. It's generally the elderly, disabled, youth and minority populations, communities of color that are disproportionately affected," said Leo Morales, communications coordinator with American Civil Liberties Union of Idaho.

A three-judge federal panel ruled Aug. 30 that Texas officials' assumption that their new voter ID requirement would not be discriminatory were "unpersuasive, invalid or both," according to Justice David S. Tatel, of the U.S. Court of Appeals.

"Even though we have that option, our concern is a lack of education across [Idaho] in regard to the affidavit option," said Morales. "Some community members and poll workers may not be trained on this properly and may still believe that photo ID is the only option."

"For Idaho, of course, our largest minority population is the Latino population," he said. "So, we're coordinating those efforts in Spanish and English."

The Texas model offered no alternative to presenting an ID card. Other states have gone as far as requiring birth certificates to prove citizenship.

Meanwhile, ACLU of Idaho is not considering challenging Idaho's voter ID law. Morales said educating poll workers and the public about the affidavit option remains its priority.

ACLU Idaho will monitor the law's effects through the November elections.

"If indeed [citizens] are denied because they didn't have a photo ID, that is definitely grounds for a legal challenge," said Morales. "We definitely are active, and we want to hear stories from Idahoans who have been refused or have had obstacles put before them."
